My family owns a marine furniture shop and I've seen vinyl do this many times. However, we dont restore, we just replace.Army-thanks for the tips. I'll probably try the tire shine since my buddy has also used it (I sent him your suggestions).
I have been using MG40 for a long time, but only as a maint/ preventative, have never tried it to restore.I highly recommend Mirror Glaze 40, It is all I've used for years. As Vinyl and Rubber age they off-gas and produce a tacky substance.
Heat (UV) is the biggest issue we have to deal with but just age alone can cause this, even sitting in the garage.
IMO ARMORALL is pure SHIT that should not be used on anything you wish to save and/or persevere.
It's greasy and the ingredients will accelerate deterioration if you do not continually re-apply, that's the hook, use more buy more.
The MG 40 is again IMO just the opposite, I will apply it twice a season with just soft cotton cloth wiping in between.
My interior, Door seals, Weather-stripping, Tires, etc. all get cleaned/protected with it and it holds up great.
